For the convenience of description, the above-mentioned devices are collectively referred to as an electronic device.

The network device may be a base station, and the base station may be configured to communicate with one or more electronic devices, or may be configured to communicate with one or more base stations with partial electronic device functions (such as communication among a macro base station, a micro base station, and an access point). The base station may be a base transceiver station (BTS) in a time division synchronous code division multiple access (TD-SCDMA) system, an evolutional node B (eNB) in a long term evolution (LTE) system, or a base station in a fifth generation new radio (5G NR) system.

The following describes an electronic device as an example of the wireless communication device and describes the case where n=2, that is, four antennas and four P ports are configured, as an example. It is to be noted that, the number of the antennas and the P ports are not limited to four, and the number thereof can be extended to 2^(n) (n being an integer and n≥2) in the implementations of the disclosure. In the case where 2^(n) antennas and 2^(n) P ports are configured, with regard to logical composition of the radio frequency circuit, physical composition of the radio frequency circuit, coupling between the independent circuit modules and the T ports, coupling between the T ports and the P ports, coupling between the P ports and the antennas, and the like, reference may be made in the following implementations. As for the principle of achieving the transmitting an SRS through the 2^(n) antennas in turn and the structure of simplified switch, reference may further be made to related descriptions in the following implementations.

At present, sounding reference signal (SRS) switching in four antennas of a mobile phone is a mandatory option for China mobile communications corporation (CMCC) in the China mobile fifth generation (5G) Scale Test Technical White Paper_Terminal, which is optional in the 3rd generation partnership project (3GPP). A main purpose of the SRS transmission is for a base station to determine quality and parameters of four channels via measuring uplink signals transmitted by the four antennas of the mobile phone in turn, to perform a beamforming of a downlink massive multi-input multi-output (MIMO) antenna array on the four channels according to a channel reciprocity, and finally to obtain the best data transmission performance for a downlink 4×4 MIMO, where 4×4 MIMO refers to that the base station has four antennas transmitting data and the terminal device has four antennas receiving data.

In order to satisfy requirements of SRS switching in four antennas, implementations of the present disclosure provide a radio frequency architecture based on a simplified 4P6T antenna switch. Compared with a 3P3T/DPDT/multiway small switch switching scheme, the present switching scheme can reduce the number of series switches in each path (all or part of switches are integrated into the 4P6T main switch), thereby reducing link loss and optimizing the overall transmission and reception performance of the terminal. The implementations of the present disclosure are described in detail below.

FIG. 1B is a schematic structural diagram illustrating a multiway switch 10 according to an implementation of the disclosure. The multiway switch 10 includes six T ports and four P ports. The six T ports include two first T ports and each of the two first T ports is coupled with all of the four P ports (that is, fully-coupled). The remaining four T ports are coupled with the four P ports in one-to-one correspondence, such that any two T ports of the remaining four T ports are coupled with different P ports. The multiway switch 10 is applicable to an electronic device 100 operable in a dual-frequency single-transmit mode. The electronic device 100 includes a radio frequency circuit 20 and an antenna system 30. The antenna system 30 includes four antennas. The four antennas correspond to the four P ports; specifically, the four antennas and the four P ports are in one-to-one correspondence.

The multiway switch 10 is configured to be coupled with the radio frequency circuit 20 and the antenna system 30 to implement a preset function of the electronic device 100. The preset function is a function of transmitting an SRS through the four antennas in turn, which can be understood as a four-port SRS function.

“P port” in implementations of the disclosure is the abbreviation of “pole port”, which refers to ports coupled with antennas. “T port” in implementations of the disclosure is the abbreviation of “throw port”, which refers to ports coupled with radio frequency circuits. According to the implementations of the disclosure, the four P ports and the six T ports are provided, and to facilitate an intuitive understanding of the structure of the multiway switch 10, the multiway switch 10 may also be referred to as a “4P6T switch”. As illustrated in FIG. 2 for example, the four P ports are embodied as P port 1, P port 2, P port 3, and P port 4.

The concept of “coupling”, “separate-coupling”, “full-coupling”, or other kinds of coupling between the T ports and the P ports of the multiway switch 10 described in the implementations of the disclosure refers to a state in which the T ports are coupled with the P ports through first switch transistors. The first switch transistors are configured to control a unidirectional conduction state between the T ports and the P ports (including a unidirectional conduction state from the T ports to the P ports and a unidirectional conduction state from the P ports to the T ports). The first switch transistor can be, for example, a switch array including three field-effect transistors (such as metal-oxide-semiconductor (MOS) transistors). When the first switch transistor is disconnected and not grounded, parasitic parameters (such as parasitic capacitances and parasitic inductances) will greatly affect performance of other connected ports. Therefore, the first switch transistor is implemented with three MOS transistors, where the three MOS transistors can be in a common source connection, that is, coupled at a common source. When the first switch transistor is disconnected, two MOS transistors at two ends are disconnected and one MOS transistor in the middle is grounded. In addition to the first switch transistors between the T ports and the P ports, the multiway switch 10 further includes second switch transistors arranged around both T ports and P ports. The second switch transistor may also be referred to as a grounding switch transistor. Each T port may be provided with a grounding switch transistor and each P port may also be provided with a grounding switch transistor. When a T port or a P port does not carry out signal transmission or reception, a grounding switch transistor around the T port or the P port is switched on. When a T port or a P port receives or transmits signals, a grounding switch transistor around the T port or the P port is disconnected. The second switch transistor is configured to enable a corresponding port (T port or P port) and can be, for example, a MOS transistor. The specific configurations of the first switch transistor and the second switch transistor are not limited herein. In one implementation, the electronic device 100 can control paths between the T ports and the P ports to switch on through the first switch transistors. As one implementation, the electronic device 100 can be provided with a dedicated controller to be coupled with switch transistors of the multiway switch 10.

The concept of “fully coupled” is defined for the T ports and means that one T port is respectively coupled with all P ports. The expression of “the first T ports are fully coupled ports” means that each of the two first T ports is fully coupled with the four P ports.

The function of transmitting an SRS through the four antennas corresponding to the four P ports in turn refers to a process in which the electronic device interacts with a base station based on polling mechanism to determine quality of an uplink channel corresponding to each antenna.

The electronic device may be a mobile phone or other terminal devices supporting the 5G NR, such as customer premise equipment (CPE) or a mobile wireless-fidelity (MIFI).

The dual-frequency single-transmit mode refers to an operating mode in which the electronic device can support dual frequency band-one uplink (UL) transmit path or dual frequency band-four downlink (DL) receive paths.

The multiway switch 10 includes field-effect transistors. Since two of the six T ports are coupled with all of the four P ports and each of other T ports is configured to be coupled with one fixed antenna for receiving, the number of built-in field-effect transistors, volume, and cost of the 4P6T switch can be reduced, and performance of the 4P6T switch can be improved as well. Details will be described hereinafter.

For example, assume that the multiway switch includes six T ports, i.e., T port 1, T port 2, T port 3, T port 4, T port 5, and T port 6 illustrated in FIG. 2, and further includes field-effect transistors; among the six T ports, if each T port is fully coupled with the four P ports, as illustrated in FIG. 2 of a schematic structural diagram of the multiway switch, the number of the field-effect transistors of the multiway switch is 6+6*4*3+4=82; if only two T ports are fully coupled with the four P ports, as illustrated in FIG. 3 of a schematic structural diagram of the multiway switch, the number of the field-effect transistors of the multiway switch is 6+(2*4+(6−2)*1)*3+4=46.

In one implementation, the electronic device 100 may further include a radio frequency transceiver. The radio frequency transceiver is coupled with the radio frequency circuit 20.

By limiting the number of T ports that are fully coupled with the four P ports (in other words, fully coupled T ports), the number of switches of the radio frequency system of the electronic device 100 can be effectively reduced. The number of fully coupled T ports has a great influence on performance of the radio frequency system.

As can be seen, according to implementations of the present disclosure, the multiway switch provided is applicable to the electronic device 100 operable in the dual-frequency single-transmit mode. The electronic device 100 includes the antenna system 30, the radio frequency circuit 20, and the multiway switch 10. The antenna system 30 includes the four antennas. The multiway switch 10 includes the six T ports and the four P ports, and two of the six T ports are fully coupled with the four P ports. The multiway switch 10 is configured to be coupled with the radio frequency circuit 20 and the antenna system 30 to implement the preset function of transmitting an SRS through the four antennas corresponding to the four ports in turn of the electronic device 100.

In one possible implementation, in addition to the two first T ports, the six T ports further include four second T ports. Each of the four second T ports is coupled with one of the four P ports and among the four second T ports, any two second T ports at the same frequency band are coupled with different P ports. Each of the four P ports is configured to be coupled with a corresponding antenna of the four antennas, specifically, one P port is configured to be coupled with one antenna and any two P ports are configured to be coupled with different antennas. The two first T ports at least support a transmission function (that is, a signal transmission function), and the four second T ports support only a reception function (that is, a signal reception function).

In one implementation, the four second T ports are configured to receive signals at a first frequency band or configured to receive signals at a second frequency band, where the first frequency band is not overlapped with the second frequency band.

In one implementation, the expression of “among the four second T ports, any two second T ports at the same frequency band being coupled with different P ports” means that second T ports operable at the same frequency band in the four second T ports are coupled with different P ports. For example, if second T port 1 is operable at the first frequency band and second T port 2 is also operable at the first frequency band, second T port 1 may be coupled with P port 1, second T port 2 may be coupled with P port 2, and P port 1 is different from P port 2.

In one possible implementation, the multiway switch 10 includes forty-six field-effect transistors.

In the case that the electronic device 100 is operable in the dual-frequency single-transmit mode, the electronic device 100 logically includes eight receiver circuits (can be comprehended as a circuit for receiving and/or processing signals) and two transmitter circuits (can be comprehended as a circuit for transmitting and/or processing signals). Since the multiway switch 10 includes the six T ports and the six T ports include the two first T ports, the number of field-effect transistors corresponding to the multiway switch 10 is 6+(2*4+(6−2)*1)*3+4=46. One of the two transmitter circuits can correspond to one first port (two first ports in total) that supports the transmission function and the first port is configured to be coupled with a corresponding first T port of the two first T ports of the multiway switch 10. In addition, two of the eight receiver circuits can correspond to one second port (four second ports in total) that supports only the reception function, where each second port is configured to be coupled with a corresponding second T port of the multiway switch 10. In this case, a schematic structure of a corresponding radio frequency circuit 20 is illustrated in FIG. 4A and a schematic structure of a corresponding multiway switch 10 is illustrated in FIG. 4B. The specific configuration of the transmitter circuit and the receiver circuit, and definitions related to the multiway switch 10 are similar to the foregoing implementations and will not be described herein again. In addition, it can be understood that, the exemplary matching manner of the radio frequency circuit 20 and the multiway switch 10 includes but is not limited to the structure of the drawings.

It can be seen that the multiway switch 10 of the implementation of the disclosure can enable the electronic device 100 to be operable in the dual-frequency single-transmit mode. It is beneficial to simplifying the radio frequency architecture of the terminal supporting four-port SRS switching in the 5G NR, reducing the number of switches in transmit paths and receive paths, and reducing path loss, thereby improving transmit power/sensitivity, data transmission rate in the 5G NR, and uplink and downlink coverage of the mobile phone, and reducing power consumption.

In one possible implementation, the radio frequency circuit 20 of the electronic device 100 physically includes at least one independent circuit module. The at least one independent circuit module includes first ports and second ports. The first ports include transmit ports, and the transmit ports are configured to be coupled with the two first T ports in one-to-one correspondence. Specifically, the at least one independent circuit module may have one or more transmit ports. The second ports include receive ports, and the receive ports are configured to be coupled with four second T ports in one-to-one correspondence. Specifically, the at least one independent circuit module may have one or more receive ports. The “transmit port” refers to a port (may be composed of one or more components) which implements a corresponding transmission function and is located on the path of one transmitter circuit. The “receive port” refers to a port (may be composed of one or more components) which implements a corresponding reception function and is located on the path after integration of receiver circuits. It should be noted that the ports such as transmit ports and receive ports illustrated in the figures are exemplary and do not intend to indicate an exact port position and impose any restrictions.

The radio frequency circuit 20 logically includes two transmitter circuits and eight receiver circuits.

Since low-noise amplifiers (LNA) in the eight receiver circuits can operate simultaneously, due to their low power and low power consumption, mutual influence can be avoided through design. Therefore, multiple LNAs in multiple receiver circuits at the same frequency band can be disposed in the same circuit module. However, two power amplifiers (PAs) at the same frequency band can work simultaneously (corresponding to UL MIMO mode), a transmit power will be high, and two signals will interfere with each other. In addition, the two PAs will affect heat dissipation efficiency when working at the same time. Two transmitter circuits at different frequency bands are provided in the implementations of the disclosure, and therefore it is necessary to provide one independent circuit module or more than one independent circuit modules.

When the radio frequency circuit 20 physically includes one independent circuit module, a schematic structure of a corresponding electronic device 100 is illustrated in FIG. 5, and the independent circuit module includes two transmitter circuits and eight receiver circuits.

As can be seen, in the implementation of the disclosure, the electronic device 100 can achieve a function of transmitting an SRS through the four antennas corresponding to the four P ports in turn of the electronic device 100 by controlling a state in which the T ports of the multiway switch 10 are coupled with the P ports of the multiway switch 10 via the switch transistors.

In one possible implementation, the four antennas include a first antenna, a second antenna, a third antenna, and a fourth antenna. These four antennas are all operable at a 5G NR frequency band.

The 5G NR frequency band may include, for example, 3.3 GHz to 3.8 GHz and 4.4 GHz to 5 GHz.

In one possible implementation, the four antennas include a first antenna, a second antenna, a third antenna, and a fourth antenna. The first antenna and the fourth antenna are antennas operable at a long term evolution (LTE) frequency band and a 5G NR frequency band. The second antenna and the third antenna are antennas only operable at the 5G NR frequency band.

The first antenna and fourth antenna are intended to support DL 4×4 MIMO for some frequency bands in LTE on terminals. These two antennas are shared with the 5G NR (hereinafter, “shared antennas” for short). The LTE frequency band may include, for example, 1880 MHz to 1920 MHz and 2496 MHz to 2690 MHz.

In one possible implementation, as illustrated in FIG. 14, the antenna system further includes a first combiner and a second combiner. The first combiner has a first port configured to be coupled with the first antenna, a second port configured to be coupled with a first receive path in LTE 4×4 MIMO) configuration of the electronic device, and a third port configured to be coupled with a corresponding P port of the multiway switch.

The LTE 4*4 MIMO is a downlink LTE receive circuit and can be defined as a third receive path. Since the LTE currently has two receive paths, in order to support LTE 4×4 MIMO, the third path and a fourth receive path are added.

According to performance of the four antennas, the electronic device will arrange one antenna with better performance for the circuit for PRX (primary receiver), and the antenna will be in a standby state. Moreover, first T ports of the switch having both the transmission function and the reception function can be configured for TX (transmit) and PRX purpose, and thus the antenna can be switched arbitrarily. In this way, there is no need to restrict the coupling between ports of shared antennas.

In one possible implementation, as illustrated in FIG. 15, the antenna system further includes a first single-pole double-throw (SPDT) switch and a second SPDT switch. The first SPDT switch has a first port configured to be coupled with the first antenna, a second port configured to be coupled with a first receive path in LTE 4×4 MIMO configuration of the electronic device, and a third port configured to be coupled with a corresponding P port of the multiway switch.

The schemes of the disclosure can be combined or replaced with each other. For example, the antenna system and/or the multiway switch described above can be applied or combined into the radio frequency system and the wireless communication device below. It is to be noted that, “the antenna system and/or the multiway switch” of the disclosure means “the antenna system”, “the multiway switch”, or “the antenna system and the multiway switch”.

In one possible implementation, FIG. 16 is a schematic structural diagram illustrating a radio frequency system according to an implementation of the disclosure. The radio frequency system includes an antenna system, a radio frequency circuit, and a multiway switch coupled with the radio frequency circuit and the antenna system. The multiway switch has a structure as illustrated in any of the forgoing implementations and figures. In one implementation, the multiway switch includes six T ports and four P ports, the six T ports include two first T ports at least supporting a transmission function and four second T ports supporting only a reception function, and each of the two first T ports is coupled with all of the four P ports. The antenna system includes four antennas corresponding to the four P ports.

The multiway switch is configured to implement a preset function of transmitting an SRS through the four antennas in turn.

In one implementation, each of the four second T ports is coupled with one of the four P ports, and T ports at the same frequency band in the four second T ports are coupled with different P ports. Each of the four P ports is coupled with a corresponding antenna of the four antennas.

In one implementation, the four antennas includes a first antenna, a second antenna, a third antenna, and a fourth antenna. The first antenna, the second antenna, the third antenna, and the fourth antenna are antennas operable at a 5G NR frequency band.

In another implementation, the four antennas include a first antenna, a second antenna, a third antenna, and a fourth antenna. The first antenna and the fourth antenna are antennas operable at a long term evolution (LTE) frequency band and a 5G NR frequency band. The second antenna and the third antenna are antennas only operable at the 5G NR frequency band.

In one implementation, with the above structure regarding to the four antennas, the antenna system further includes a first combiner and a second combiner. The first combiner has a first port coupled with the first antenna, a second port coupled with a first receive path in LTE 4×4 MIMO configuration of the radio frequency system, and a third port coupled with a corresponding P port of the multiway switch. The second combiner has a first port coupled with the fourth antenna, a second port coupled with a second receive path in the LTE 4×4 MIMO configuration of the radio frequency system, and a third port coupled with a corresponding P port of the multiway switch.

In one implementation, with the above structure regarding to the four antennas, the antenna system 20 further includes a first single-pole double-throw (SPDT) switch and a second SPDT switch. The first SPDT switch has a first port coupled with the first antenna, a second port coupled with a first receive path in LTE 4×4 MIMO configuration of the radio frequency system, and a third port coupled with a corresponding P port of the multiway switch. The second SPDT switch has a first port coupled with the fourth antenna, a second port coupled with a second receive path in the LTE 4×4 MIMO configuration of the radio frequency system, and a third port coupled with a corresponding P port of the multiway switch.

As can be seen, for the transmit paths and the receive paths of the radio frequency system of the electronic device, the transmit paths can include one single independent switch (a 4P6T switch) or two independent switches (a SPDT switch and a 4P6T switch) and the receive paths can include one single independent switch (a 4P6T switch) or two independent switches (a SPDT switch and a 4P6T switch). That is to say, by integrating more switch functions of the transmit paths and the receive paths of the radio frequency system into the 4P6T switch, the number of independent switches of the transmit paths and the receive paths can be effectively reduced.

In one possible implementation, FIG. 17 is a schematic structural diagram illustrating a wireless communication device according to an implementation of the disclosure. The wireless communication device for example can be a wireless communication device, such as a mobile terminal, a base station, or the like, and includes an antenna system, a radio frequency transceiver, a radio frequency circuit coupled with the radio frequency transceiver, and a multiway switch coupled with the radio frequency circuit and the antenna system. The multiway switch can be the one described in any of the implementations above.

The multiway switch includes six T ports and four P ports. The six T ports include two first T ports, and each of the two first T ports is coupled with all of the four P ports. The antenna system include four antennas corresponding to the four P ports.

The multiway switch is configured to implement a preset function of transmitting an SRS through the four antennas in turn.

In one implementation, the six T ports further comprise four second T ports. Each of the four second T ports is coupled with one of the four P ports and T ports at the same frequency band in the four second T ports are coupled with different P ports. Each of the four P ports is coupled with a corresponding antenna of the four antennas, the two first T ports at least support a transmission function, and the four second T ports support only a reception function.

In addition, as illustrated in FIG. 18, the four antennas in the antenna system described in the implementations of the disclosure can also be multiplexed by a wireless charging receiver of the electronic device. The wireless charging receiver includes a receive antenna and a receive control circuit. The receive antenna matches transmit antennas of a wireless charging transmitter (resonates at the same or similar frequency and transfers energy in a wireless manner in the way of radiative resonant magnetic coupling). The receive control circuit converts, through a loop array antenna, the energy into a direct current (DC) to output to charge a battery. The receive control circuit can dynamically adjust a frequency of the loop array antenna and match the frequency of the loop array antenna with frequencies of the transmit antennas of the wireless charging transmitter to achieve paired charging. Alternatively, the receive control circuit interacts with the wireless charging transmitter in real time on a frequency change range to implement an “exclusive encryption” wireless charging mode.

The receive antenna may be an antenna including at least one of the four antennas (in the case of multiple antennas, the multiple antennas are strobed via switches).

For example, as illustrated in FIG. 19, the receive antenna is a loop array antenna including the four antennas described above. The four antennas include antenna 1, antenna 2, antenna 3, and antenna 4. Antenna 1 and antenna 4 are operable at both an LTE frequency band and a 5G NR frequency band, while antenna 2 and antenna 3 are only operable at the 5G NR frequency band. A port of antenna 1 and a port of antenna 4 are used as ports of the loop array antenna. Adjacent antennas are coupled via a gate circuit 170 with an isolation function. The gate circuit 170 includes a spacer 171 and a switch 172, where the spacer 171 is a conductor and the switch 172 is further coupled with a controller. The electronic device can conduct the switch 172 of each gate circuit 170 in a wireless charging mode to form a loop array antenna to receive energy. By adding the spacers 171 among the antennas, the gate circuit 170 can reduce mutual coupling among the multiple antennas of the electronic device in a normal communication mode, improve isolation among the multiple antennas, and optimize performance of the antennas. On the other hand, the multiple antennas can be coupled in series to form the loop array antenna through the switches 172, so as to better match the transmit antennas to transfer energy. Furthermore, since the capabilities of antenna 1 and antenna 4 are stronger than those of antenna 2 and antenna 3, the loop array antenna thus arranged can reduce energy loss in transmission as much as possible.
